ISL33001, ISL33002, ISL33003 FN7560
Rev 6.00
July 11, 2014 I2C Bus Buffer with Rise Time Accelerators and Hot Swap Capability
The ISL33001, ISL33002, ISL33003 are 2-Channel Bus Buffers
that provide the buffering necessary to extend the bus
capacitance beyond the 400pF maximum specified by the I2C
specification. In addition, the ISL33001, ISL33002, ISL33003
feature rise time accelerator circuitry to reduce power
consumption from passive bus pull-up resistors and improve
data-rate performance. All devices also include hot swap circuitry
to prevent corruption of the data and clock lines when I2C devices
are plugged into a live backplane, and the ISL33002 and
ISL33003 add level translation for mixed supply voltage
applications. The ISL33001, ISL33002, ISL33003 operate at
supply voltages from +2.3V to +5.5V at a temperature range of
-40В°C to +85В°C. Summary of Features
